To be precise: 1. const data are readable before and after relocation. 2. non-const initialized data are readable only until relocated, and then writable as well. 3. BSS data cannot and must not be used at all until relocated, and are then zeroed out before board_init_r() starts. > Best Regards, > Reinhard Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
